commitec97e11298upstream. Commit572086325c("Drivers: hv: vmbus: Cleanup synic memory free path") says "Any memory allocations that succeeded will be freed when the caller cleans up by calling hv_synic_free()", but if the get_zeroed_page() in hv_synic_alloc() fails, currently hv_synic_free() is not really called in vmbus_bus_init(), consequently there will be a memory leak, e.g. hv_context.hv_numa_map is not freed in the error path. Fix this by updating the goto labels.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
